ROBERT LEITCH, OF BALTIMORE, MARYLAND.

IMPROVEMENT IN TWO\WAY STOPFCOCKS.

Specification forming part of Letters Patent No. 36,222, dated August li), 1862.

To all whom it may concern:

Be it known that I, ROBERT LErroH, of Baltimore, in the State of Maryland, vhave invented a new and Improved Stop Cock for Street and Dwelling Purposes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which like letters designate the saine parts, and in which drawingsf Figurel is a longitudinal vertical section showing the flow of water through the main passage of the stopcock, and also through the main channel of the valve; Fig. 2, a like view showing the valve so turned as to cause the water to flow only through the main channel of the stop-cock; Fig. 3, a partial horizontal section showing the flow of water only through that portion of the main channel of the stopcock which is between the valve and the fountain head, and also through the main channel of the valve; and Fig. 4, a partial horizontal section and plan with the valve so turned as to entirely eut oli` the iow of water through my stop-cock for streetand dwelling purposes.

The nature ofrm'y invention consists in so constructing a stop-cock for street and dwelling purposes that the flow of the water may be equally divided, or nearly so, for use in the street and in a dwelling-house or other locality at one and the same time, or so that the full ow of the water may be used solely in the dwelling-house or other locality and not in the street, or so that the full flow of the water may be used solely in the street, or be cut ofi' at the same time both from the street and the dwelling-house or other locality, as may be desired.

To effect this I construct the mainportion A of my stop-cock of metal, in one piece, with a longitudinal main channel, ff, through the same, and with a vertical conical opening through its center to receive a valve,Y B, as shown in the figures. The valve B is provided wit-h a vertical conical opening or channel, f, commencing at its top a and extending down nearly two-thirds its length, and so as to register, by means of slots or openings f3 and f5, with the channel f2, which latter channel leads into the main channel f f of the main portion A, as shown in the figures. This valve is cast of metal, in onepiece, and at its bottom terminates in a screw-shank, c,

fitted to receive Aa screw-nut, d, so that when the nut d is screwed up the top of the nut will abut against the shoulder c of the main portion A and thus draw the valve down firmly and snugly into its seat. The lower portion of the valve has a vertical slot or opening cut through it, as at f4, which slot registers or communicates with the main channel ff of the main portion A. Between the point la2 and the valve Rand adjoining the valve, it will be observed that the main portion A of my stop-cock is enlarged, as shown, so as to permit of a passage or channel,f2, for the iiow ofthe water from a portion of the main channelf into the channel f of the valve B; and, as before stated, vertical slots or openingsf3 andf5 are made, or maybe made, in the valve B, so as to connect thepvertioal conical opening f of the valve with the channel f2. As shown clearly in Fig. 2, a vent-hole, e, is provided to allow of the water to waste out of the vertical opening f of the valve B, when desired.

With Vmy apparatus thus constructed, one of its ends, a2, being secured to a pipe leading to the fountainhead and itsl opposite end, a3,

connected with a pipe leading to a dwelling y or other locality, and with a hose connected to the top a of the valve B, I am4 enabled to wash the street at the same time the dwelling is supplied with water, as shown inl Fig. l; or the water may be cut on" from the street and only supplied to the dwelling, as shown f in Fig. 2; or the Water may be out off'froni the dwelling and only supplied to the street, as shown in Fig. 3; or the water may be entirely out off both from the dwelling and the street, as shown in Fig. 4.

Having thus described my stop-cock for street and dwelling purposes, what I claim as new, and desire to secure by Letters Patent of the United States, is y A stop cock for street and dwelling purposes constructed and operating substantially inthe manner and for the purpose .set forth. Vitness my hand and seal, in the matter of my application for a patent for a stop-cock for street and dwelling purposes, this 16th day of April, A. D. 1862.
